    Abstract : Diabetes mellitus (DM) is one of the leading causes of end stage renal failure. An increased susceptibility to renal ischemia/reperfusion (I/R)-injury was found in DM rats. Unilateral renal ischemia for as short as 20 minutes led to an irreversible progressive injury in DM kidneys, whereas the injury in non-DM kidneys was almost reversible. READ MORE
